dpdk: remove dead code
rte_eth_tx_burst() returns the number of packets actually stored in transmit descriptors and the return type is uint16. n_sent cannot be negative and the if branch is dead code. Type: improvement Change-Id: Idc2980d342756c1093ddf74ea6207d072e819331 Signed-off-by: Benoît Ganne <bganne@cisco.com>
